tomo_scan() only reset the timing/ETA fields, so after a finished scan the
progress GUI kept showing the old subtomo, angle and projection == total
(rings at 100 %) while the initial 0-degree reference shot ran, with an ETA
computed from the old projection count against the new start time.
New _reset_progress_for_new_scan() resets every field (incl. the right
totals for the tomo type) in one global-var update and refreshes the GUI.
Resumes are unaffected.
